Description

Technical field [0001] The present invention belongs to the field of drug metal organic skeleton material synthesis, and specific to a method and method and method for synthesizing a metal organic skeleton material based on microfluidic aperation method. Background technique [0002] Zegelediimidazole skeleton material ZiF-8 composed of zinc ion and 2-methylimidazole (HMIM) is in the form of a metal organic skeleton material (MOFS) due to its orchestral structure, and has become a metal organic skeleton material (MOFS). Most, one of the most potential microporous materials, ZiF-8 exhibits a broad application prospect in the field of gas adsorption separation, catalysis, and in vivo delivery. In addition to the general advantage of such materials, ZIF-8 has the characteristics of hydrothermal stability and acid instability, which provides possible to construct a pH response drug delivery system. For example, there is a tumor intracellular environmental bleeding (pH 4.0-6.0), and t...
